New states in the positive parity yrast bands of $\sp{74}$Se and $\sp{77}$Kr have been observed with the reactions $\sp{52}$Cr($\sp{28}$Si,$\alpha$2p)$\sp{74}$Se and $\sp{52}$Cr($\sp{28}$Si,2pn)$\sp{77}$Kr at 98 MeV. The target consisted of approximately 1 mg/cm$\sp2$ natural chromium (84% $\sp{52}$Cr abundance) evaporated on a thick lead backing. / The new states extend the known level scheme of $\sp{74}$Se up to I$\sp{\pi}$ = (22$\sp+$) and most of the transitions in the other previously reported bands have been seen. For the states I$\sp{\pi}$ $\geq$ 6$\sp+$ the spectrum shows a relatively constant moment of inertia parameter $(\hbar\sp2$/2$\Theta)$ = 27.8 $\pm$ 0.5 keV. / Excited positive parity states up to spin (41/2) have been observed in $\sp{77}$Kr. $\Delta$I = 1 transitions have been identified throughout the positive parity band. The energies, mixing ratios and B(M1) transition rates for these transitions alternate in size as the spin increases. A cranked shell model analysis was performed along with Strutinsky-Bogolyubov cranking calculations. The observed decrease in the signature splitting of the $\nu$g$\sb{9/2}$ band has been attributed to a band crossing due to an aligning pair of g$\sb{9/2}$ protons. Prolate quadrupole deformations of $\beta\sb2$ = 0.34 for the ground band and $\beta\sb2$ = 0.26 for the first excited band are predicted. This band crossing is associated with a shape change caused by the polarization effect of aligned quasiparticles. / Source: Dissertation Abstracts International, Volume: 49-03, Section: B, page: 0803. / Major Professor: Samuel L.

In the Standard Model, meson properties are ultimately features of the theory of quantum chromodynamics (QCD), and exact solutions of QCD would yield, in principle, all properties of mesons (and hadrons, in general). However, at this time, an exact solution does not exist, forcing one to turn to the use of models to describe mesonic properties. Such models are not QCD but incorporate properties of QCD in an attempt to describe hadrons in a unified framework. Furthermore, since mesons are strongly-interacting relativistic systems, one prefers to work within a formalism which is both relativistic and covariant. In this work, a study of mesons is carried out using one such model--the instantaneous Bethe-Salpeter formalism. Initially, mesonic spectra are examined with the model; however, one generally wishes to describe dynamic properties of mesons, such as transitions, form factors, response functions, etc. To this end, a covariant extension of the instantaneous condition is introduced and used to develop a covariant means of calculating dynamical properties, with the instantaneous Bethe-Salpeter solutions as its support. The formalism is illustrated for a calculation of the electromagnetic form factor of the pion. / Source: Dissertation Abstracts International, Volume: 56-03, Section: B, page: 1498. / Major Professor: Jorge Piekarewicz. / Thesis (Ph.D.)--The Florida State University, 1995.
